Full-service customs brokerage for cargo crossing the US-Mexico border. A licensed customs broker files CBP Form 3461 (entry/immediate delivery) and Form 7501 (entry summary) on every shipment, backed by AI-powered HTS classification, automated PGA screening, and electronic CATAIR/ABI filing directly into CBP ACE.
Filed before or at the time your cargo arrives at the US port of entry. This form requests release of your merchandise from CBP custody. For qualified shipments, we file for immediate delivery so goods are released the same day they arrive, without waiting in a bonded warehouse.
Filed within 10 business days of cargo release. This is the complete duty declaration — every line item with its HTS classification, declared value, duty rate, and applicable fees. We calculate MPF (Merchandise Processing Fee at 0.3464%), HMF (Harbor Maintenance Fee), and any ad valorem surcharges including Section 301 and IEEPA duties.
Every product is screened against all 16 Partner Government Agencies before filing. If your shipment contains food, the FDA prior notice is generated. If it contains alcohol, TTB requirements are flagged. Agricultural products trigger APHIS review. You never get a CBP hold because of a missed agency requirement.
All entry data is transmitted electronically to CBP through the Automated Broker Interface (ABI) using CATAIR record formats. SE records for entry data, AE records for entry summary, and OI/PG records for PGA data. No paper, no manual data entry — your filing is in CBP ACE within seconds.
Provide a product description, commercial invoice, or just a photo. Our AI engine ingests any format — text, PDF, or image — and extracts the data needed for classification.
Total landed cost is computed deterministically: base duty rate, MPF (0.3464%), HMF ($0.125/1000 lbs), any Section 301/IEEPA surcharges, and USMCA/T-MEC savings. Every number cites its legal authority.
CATAIR records (SE, AE, OI/PG) and X12 EDI documents are generated and transmitted to CBP ACE via ABI. Your cargo is released, often within minutes of vessel or truck arrival at the port of entry.
Every entry is signed by a licensed customs broker, fully compliant with CBP H350722 guidelines. We are the broker of record — not a software tool pretending to be one.
AI classification in under 100ms means your entry paperwork is ready before your truck reaches the border. No manual tariff lookups, no spreadsheet guesswork.
All 16 US Partner Government Agencies are screened automatically: FDA prior notice, TTB for alcohol, APHIS for agriculture, EPA for chemicals, CPSC for consumer goods, and 11 more.
If your product qualifies under USMCA rules of origin, we identify the savings and file the preferential claim. Many importers overpay duties simply because nobody checks eligibility.
Physical presence and carrier relationships at the two busiest US-Mexico land ports. Whether your cargo crosses by truck, rail, or ocean via Long Beach, we cover the corridor.
No monthly minimums, no hidden surcharges. You pay per entry filed. High-volume shippers get tiered pricing that drops as volume grows.
